Aaaah lansing... ! I suppose that in the street, we recognize you immediatly ! You are the guy who never smiles ! Am I right ?

But thanks for your answer !

In fact, I thought that maybe somebody could have an idea about the logic of the filters they used or what they did, that's all ! Because there are lots of professionnals and persons who have great ideas here !

Finally, I will not change the gamma and the levels, because I tried something and I understood !

I add scanlines on one of my picture, and when I observe, it was equivalent to the same picture with the gamma to 2.5 instead of 2.2.

So, I conclued that the scanlines from the CRT screen affected the gamma and the general luminosity of the picture. And it's not a question of levels.

A gamma of 2.2 on a CRT looks like a gamma of 2.5 on a modern display, because of the technology that it used.

The other problem is, that I shoud change the gamma for all my videos, and I don't think it's the good thing to do. It's better to calibrate a screen to a certain gamma rather than to change the gamma of videos.

And if Higan propose to have a color filter that we can activate or not, it's just for a certain representation of what the CRT were. It doesn't respond to an objective will.

Voilŗ ! J'ai tout dit !

(I know it's not exactly representative of the reality, but these pictures are just for the examples)

He recommended that you could ask numbers from higan devs.
And your response was plain insult.

You asked good script for your videos. And you seemed to like your current script.Others might think it might be useful for their videos. Tastes are not universal.

It wasn't an insult ! I have nothing against him, even if sometimes, I think he could speak on a nicer tone !

Because he answers this too :

Why add this ?

But I don't want to speak against him. Maybe I'm too sensitive ! Who knows ?

But you know, I often say the same thing to my brother, that he's sometimes too serious and must smile a bit more, but it's just to free him ! Not to mock him ! And it doesn't take it incorrectly.

I'm not a person who hates others. Sometimes it's hard to retranscribe by words the emotions of what we think. Maybe there were some misunderstanding.

I thought it was ironic ! Sorry ! But I didn't take it bad, no problem I have a lot of self-derision

Note : Here, the aspect ratio is wrong if we compare with other videos from the Legacy of Kain saga and the aspect ratio in-game. After we cropped, we get a resolution of 640x320. We must have an equivalent of 640x360 to get a correct AR.

I could kill myself, because I already encoded all my videos, but I need to change something I'm sure that you expected this moment... no ?

But I must put this :

"pscrn=2"

instead of this :

"pscrn=3"

But for all the rest, I'm satisfied !

To explain this change, I will just say that something disturbed me with the relief and the perspective. But it's more disturbing in movement I think.

It wasn't completely natural. My error was that I wanted a copy of the image of the Super NT. In fact I was confused ! I didn't know if I wanted a image like it is on a modern or CRT display, or both...

When we compare the PS1 picture on a modern display and on a PVM, we can noticed that the scanlines on the PVM tend to soften the angles and the aliasing.

On the PC picture, it's already good, equivalent to the PS1 version on a PVM.

It's the things that I forgot ! So, it was like if I tried to have a PS1 image on a modern display, thinking that I would get a PS1 image on a PVM

Do you follow me ?

There was a little gap with the "pscrn=3". I thought it would recreate the information between scalines, to get a image like the PC version of Tomb Raider for the comparison, but it already recreated this information with "pscrn=2".

I tried, and it's the same effect that have the PS1 version on a PVM or the PC version of Tomb Raider, but for a Super Nes game :

I come back to you, because I thought about one thing... an important thing !

As some of you know, Higan is the perpect emulator, close to the original experience of the Super Nes, but on the modern display

But I asked myself, how they did to reproduce the original colors, which are darker. Is it simply a way to imitate the feeling of the old CRT display ? I think yes and no... maybe !

I thought one thing : my pictures are in RGB 24 bits, so the levels are 0-255.

But at the time of the CRT display, maybe it was meant to be display in a equivalent of RGB 16-235.

No ?

I tried this, and in fact, my image was close to the image of Higan, even if not exactly (maybe the gamma).

After some other researches, I read that the gamma of the CRT was close to 2.5 too if we compare to the gamma of 2,22 on a modern display.

So I convert the gamma of the image too

Actually :

1 / 0,45 = 2,2222222222222222222222222222222

So I calculated :

2,5 / (1 / 0,45) = 1,125

So, I used this function to transform my gamma and my levels :

And really, it's closer of what I remember of my experience on a CRT display !

Just for the example, the picture of Mr. Nutz with the spider, I remember how it was dark on my CRT screen when I was a child. It really was a dark atmosphere, the moon was very present, like almost the only comforting glow...

By the way, I was always surprised to see that it's so clear on my LCDs with an emulator

With "pscrn=3" instead of 4, I noticed that it's closer that what I remember. And yes, I can see the difference !

I compare in zooming with the original picture of Killer Instinct and a the picture of the same game in a video of the Super NT (a real Super Nintendo HD, not an emulator), and it's closer now !

With "pscrn=2" and "pscrn=4", there was something weird. It didn't perfectly match !

NTSC is YIQ, an analog form of YUV, in which signals between 53.6mV and 714mV are converted to RGB between "pure" black and white, at least to whatever limits your crappy TV could achieve. "Correct" color rendering under NTSC is a polite fiction that anyone who ever created or edited content knew was a dirty, dirty lie. "Never The Same Color" is its unofficial nickname.

Byuu picked the colors he did based as closely as possible to an ideally calibrated NTSC monitor, with a bit of haircut off the top to average in the effect of the phosphors dimming every field. It has nothing to do with 16-235, which was a concept not invented until digital video. No game console would use that until HDMI appeared. This task is purely subjective, purely for your own appreciation, and you should pick a scheme that looks aesthetically pleasing to you, not seek a holy grail of perfection that doesn't actually exist.

Thanks for the explanations !

Yes, you are right, what I did is only for my own appreciation It will never be perfect, I know. When I say it's perfect, it's just a way to express my contentment I'm aware of the limits of what I do, even if I try to do as if there were none.

Otherwise, I wouldn't try anything

If I share my scripts, it's precisely because it's subjective, and because maybe somebody would prefer another of my old scripts or something else that another person posted, because there are lots of interesting things !

It's really great ! I love the aspect ! But unfortunately, I don't think it's very adapted to YouTube

But for playing (not too close of the screen), it's cool ! Thanks for all this !

Otherwise, I found some interesting videos from the "RaphaŽl Guesqua" channel.

For information, Raphael Guesqua composed the music of the video game "Mr. Nutz"

"RaphaŽl Gesqua's professional career began in the video games industry, in the early 1990s, under his real name RaphaŽl Gesqua, after he was previously known in the middle of the 16-bit demoscene, under the Audiomonster pseudonym adopted in 1989.

The composer worked with game designers, such as Paul Cuisset, for whom he arranged the soundtrack of the video game Flashback, for the Commodore Amiga, in 1992. The game has remained the world's best selling French video game.

He also worked twice with Pierre Adane, creator, among other things, of the Top Spin video games series, and for which he composed the soundtracks of Snow Bros video game, for Commodore Amiga, in 1991 (that production was cancelled for at the last minute for legal reasons), and in 1993, for Mr. Nutz,a side-scrolling platformer released for Super NES, Mega Drive/Genesis and Game Boy, which was a great success and went out of stock, just days after its release."
